[QGIS-Developer] gpkgext_relations table in gpkg?

[Richard Duivenvoorde]

Hi Devs,

via: 
https://gis.stackexchange.com/questions/338640/foreign-keys-in-geopackage
I found:
http://docs.opengeospatial.org/is/18-000/18-000.html#_gpkgext_relations
which was new to me...
BUT for QGIS seems pretty helpfull in finding foreign key relations for domain/lookup tables/widgets?

Anybody experience/examples with this?

Regards,

Richard Duivenvoorde
